Prior to Aeschylus, tragedy had been a dramatically limited dialogue between a chorus and one actor. Aeschylus added an actor, who often took more than one part, thus allowing for dramatic conflict. He also introduced costumes, stage decoration, and supernumeraries. In addition, Aeschylus also appeared in his own plays.
In the sophisticated theology of his tragedies, human transgressions are punished by divine power, and humans learn from this suffering, so that it serves a positive, moral purpose. At their best, his choral lyrics are rivals of the odes of Pindar. The choruses, more important in Aeschylus than in his successors, both comment on the action as well as present it. Vivid in its character portrayal, majestic in its tone, and captivating in its lyricism, Aeschylus' tragic poetry is esteemed among the greatest of all time. He alone of Greek tragedians was honored at Athens by having his plays performed repeatedly after his death.
